Abstract
Virtualization is a now proven software technology that is rapidly transforming the IT landscape and fundamentally changing the way people make computations and implement services. Recently, all major software producers (e.g., Microsoft and RedHat) developed or acquired virtualization technologies. Our institute (http://www.cnaf.infn.it) is a Tier1 for experiments carried on at the Large Hadron Collider at CERN (http://lhc.web.cern.ch/lhc/) and is experiencing several benefits from virtualization technologies, like improving fault tolerance, providing efficient hardware resource usage and increasing security. Currently, the virtualization solution we adopted is xen, which is well supported by the Scientific Linux distribution, widely used by the High-Energy Physics (HEP) community. Since Scientific Linux is based on RedHat ES, we felt the need to investigate performances and usability differences with the new kvm technology, recently acquired by RedHat. The case study of this work is the Tier2 site for the LHCb experiment hosted at our institute; all major grid elements for this Tier2 run on xen virtual machines smoothly. We will investigate the impact on performance and stability that a migration to kvm would entail on the Tier2 site, as well as the effort required by a system administrator to deploy the migration.
